In a fractured Madrid of the future, a family finds itself together, only to be shadowed by peril. Julia’s desperate act to save a child from cruelty unleashes a cascade of devastating repercussions.

Hugo requests that Julia assume the identity of her twin sister, Sara, in order to obtain the necessary paperwork for Marta’s retrieval. Meanwhile, the police continue their investigation into the murder of Merida.

Despite facing grave consequences, Alma persists with her medical experiments on the children. Julia mourns her loss deeply. Meanwhile, Álex finds himself forging a new friendship.

Hugo, deeply troubled, and Julia, equally distressed, pressed Luis for an explanation of their findings at the CIM, a demand that spurred Alma to swiftly begin her efforts to conceal the truth.

Emilia implored Julia to flee. As the CIM faced scrutiny, Alma brought a surprise to Hugo. Meanwhile, Daniela sought assistance in reuniting a child with his father.

Alma marked her advancement with a celebratory gathering, a lively affair where Luis received a veiled warning regarding a clandestine government undertaking. Meanwhile, Hugo stumbled upon a startling revelation.

Consumed by grief, Luis throws himself into assisting a pregnant woman who speaks of the government with alarming accusations. Meanwhile, Alma arranges a meeting with the president.

Sergio’s visit to Sector 2 yielded a startling discovery. Enrique confided in Alma that Luis was becoming overly inquisitive, prompting her to confront him directly.

Julia and Hugo earnestly requested that Luis agree to meet Sergio’s parents. As Marta surveyed the gathering, she recognized several familiar faces, prompting Álex and Emilia to devise a plan.

The bus ride to work offered Manuela an unsettling experience. Elsewhere, the parents of the vanished children persisted in their gatherings, a quiet vigil of shared grief and hope. Meanwhile, Emilia faced escalating threats.

Iván’s sudden illness struck with brutal force, and Alma implored Alejo to pursue any course necessary for his recovery. Meanwhile, Fernando wrestled with the unsettling words Emilia offered regarding his son.

The president charged Luis with delivering a speech of considerable weight, though one built on a foundation of falsehood. With assistance from Hugo, Julia embarked on a perilous course, striving to safeguard Manuela.

As the contagion swept through New Spain with relentless speed, claiming victims from all walks of life, a tide of rebellion swelled among its people.
